Application filed March 12, 1910. Serial No. 548,907.

To all whom it may concern:

Be it known that I, PETER G. KLoTz, a citizen of the United States of America,' resid- 'ing at Sandusky, in the-county of Erle and State of Ohio,

have invented certain new and useful Improvements in Machines for Manufacturing Paper Boxes and Cartons, of which the follmving is a specification, reference being had therein to the accompanyseries The invention relates to machines for making paper boxes or cartons, and of the type in which a flat blank of paper board is fed through the machine, and-is slitted "and scored in transverse directions to form a of fcldahle sections which may be bent to form a box of rectangular form.

It is the particular object of the present invention to obtain a construction in which views similar to Fig. 4, showing the-parts in different positions of adjustment; Fig. 7 is a sectional elevation of one of the longitudinal scoring disks; Fig. 8 is an enlarged section on line'X-X, Fig. 7; Fig. 9 is an elevation of one of the slitting knives; Figs. 10 and 11 are respectively an elevation and a section of one of the teeth of said knife; Fig. 12 is a plan view of a slitted'and scored blank forming the product of-the machine;

Fig. 18 is an elevation of the auxiliary cutter; and Figs. 14 and 15 are sections respectively through the lower and upper slitting cutters.

A is the frame of the machine upon which is mounted the feed table 13. C are laterally adjustable guides above this table between which placed. v a D is-a carrier for feeding the blanks from the table and into engagement with the slitthe blank to be operated upon is ting and scoring. devicesarranged in rear thereof. 7 These slitting and scoring devices forms of boxes or cartons,

operating lower slitter F is o are adapted to tyim the blank to the pro er size and divide the same into folda le sections.

As has been stated, it is one of the objects of the invention to adaptthe machine to a large variety of work, varying not only in size of the blank, .but in the dimensions and proportion of the foldable sections thereof. This frequently necessitates a complete change in adjustment of the various elements of the slitters and scoring members, and without special provision such adjust- OF SANDUSKY, OHIO, .ASSIGNOR TO THE HINDE AND DAUCH PAPER OHIO, A CORPORATION OF OHIO.

ment would require the expenditure of considerable time, as well as skilled accuracy and calculation on the part of the operator.

I have avoided such ditiiculty first, by providing means for quicklyreleasing and resetting the various elements; second, by providing exchangeable and interchangeable units; and, third, by g-raduations in the various members to facilitate accuracy in setting.

The slittin and scoring of the blank longit udinally t iereof is accomplished by a series of pairs of wheels or disks E, E, F, F, etc, which are secured respectively to transversely-extending shafts G and H mounted on the frame above and below the plane of feed. These disks or wheels are longitudinally adjustable upon their respective shafts, but are rotatively fixed thereon preferably by a key or feather I engaging corresponding keyways in the hub I of the wheels. These hubs are also preferably split and are provided with tapering clamping rings I having a threaded engagement thereon by means of which the hub ma be quickly clamped or released. The end isks of the series carry slitters for trimming the blank to the proper width, while intermediate these trimmers are disks carrying longitudinal scoring devices.

disks provided with se blades for use in the manu mental slitting acture of special having sections of different widths. The detailed construction of these devices is preferably as tion of which is provided with a threaded section J and an outwardly-extending flange J. J 2 isan annular slitting blade adjacent to the flange J, a'ndJ is a clamping collar engaging the threaded-portion J and securing a slitter to the fian e. The 00- a similar There are also follows: E is the upper trimmer, the rim poras to maintain the blade in contact with that construction, having an outwardly-extending flange K and an annular slitter cutter K, and a third clamping collar K Boththe slitter and its clamping members are laterally yieldably secured upon the disk, so

of the upper member. Thus the flange K is a separate member from the rim K of the disk, which rim is provided with recesses containing springs K bearing against an inwardly-extending portion K of the flange, while shoulders K serve to limit the movement of the flange on the rim.

Intermediate the end slitting cutters are the segmental slitting and scoring devices. The former are used only where there are sections of the blank of lesser width than the main section, and are similar to the construction already described, with the substitution of the segmental blades for the annual continuous slitter blades. The scoring members are also formed in segments for the purpose of producing offset scores in the blank to compensate for the thickness of the material and to permit one" section in fold.- ing to overlap another. The construction which I preferably use comprises a rim member L having an undercut flange or v tions.

bearing thereon forming a seat for one sideof thesegme'ntal scoring members L which are clamped byxsegmental blades L secured by tapv bolts L or other suitable means. The segmental "members L are provided with outwardly-extending flanges or beads L which are Olfest from the central plane ofthe member. This offset is of suflicient extent to produce the desired offset in the scoringwhen the members L are reversed in posltion on the rim L, and thus the same element may be used for forming either one of the offset scores. The segmental members L"are preferably also formed in short sections, which will permit of obtaining almost anydesired effect by combining a sufficient number of said sections arranged in either one or the other of their reverse posi-. The scorin members just described are secured upon the upper shaft G, and the; cooperating member upon the lower shaft may be merely a disk or wheel havin a plain rim, for supporting the work during the scoring operation.

'Both the segmental slitting cutters and the segmental offset scori members must be accurately set in relatlon to the feed 'mechanism for the blank. This is facilitated. by providing graduations upon the rim of the disk or wheel, as indicated at M,

in Fig. 7 The shaft or arbor G, upon which the disks are adjustably secured, is also preferably provided With gradations ex tending longitudinally thereof to assist in ad usting andsetting for different kinds of work.-

rear of the longitudinal slitting and scoring devices are transverse slitting and scoring members comprising a pair of drums N N of similar construction mounted upon shafts O and 0 above and below the plane of feed. Each of these drums is formed with a plurality of circumferentially-extending undercut grooves P for receiving the heads of the clamping bolts P engaging holders Q for the slitting and scoring blades. These holders referably extend the entire length of the drum, and may be adjusted to any position desired by loosening the nuts of the bolts P and moving the latter around the slots P. Graduations R are placed upon the drums preferably at opposite ends thereof to assist in accurately positioning the holders Q, the graduations of one drum running in opposite direction from those'of the other. In the holders the slitting blades and scoring bars are clamped preferably by set screws Q, and the ar-' rangement permits of adjusting the blades longitudinally into any position required;

One blade S extends continuously the entire width of the blank and is used for trimming the blank to the proper length.

stock the point will first be inserted and the 105 cutting w1ll be eflected in opposite directions by the sharpened sides of the teeth until the stock-is completely severed.- This construction reduces the resistance which would be offered by a blade having a straight edge.

Godperatmg with the blades are shearing edges, which are secured in the holders .Q

bers U arepreferabl formed with an undercut groove U' t erein, the mouth of which is of sufiicient width to receive the of the lower drum. These codperating memblade, while the lower" portion is of greater width to permit the c ange in angularity of the blade due, to the rotation of the drums. The effect. ofthe construction is that the stock is supported upon both sides of the cutter, which prevents tearing or distortion. The scoring transversely of the blank is accomplished by score bars V, which are clamped in the holders Q, and where slits.

and scores in the blank are in alinement, the

. same holder Q and clamping plate T are used for holding the score bars V and blades S S.

Inoperation, paper board blanks 'of suitable size are successively placed upon the table B, from which they are periodically 13ovices upon the fed by the carrier D between the disks or wheels E and F. The slitting blades 'upon the. end wheels will trim the blank to the roper wilth and size, and the score bars will effect the crushing down or creasing of the material along the lines which are to be subsequently bent. The segmental blades S will also operate to trim certain sections to a lesser width where boxes or cartons of this type are manufactured. After passing by the disks E and'F a blank passes between intermediate pairs of feed rolls WV, and is advanced thereby into engagement with the transverse slitting and scoring dedrums N N. These operate as has been described, scoring the blank transversely, and also slitting the ends thereof between sections. that fall in opposite directions, and finally trimming off the end to reduce the blank to the proper length.

Whenever the size or form of the box or carton is changed, adjustment'is made first by loosening the disks E and F upon their respective shafts by unscrewing the clamping nuts P. The disks are then properly spaced and set by the assistance of the longitudinal gradations upon the shafts G and H, and are clamped by again tightening the nuts I The next adjustment is that of the score members L, which are set with reference to the gradations M upon the rim L. If longer or shorter segments are needed than those prevlously used the clamping.

plate L is detached to permitof exchangmg or reversing one or more of the members L. The segmental slitting blades S are also set by the assistance of the gradations upon the rim of the wheel or disk carrying the same. Thus all of the members operatmg longitudinally upon the blank are properly positioned.

The transverse scoring and slitting devices'are next positioned by loosening the holders Q and adjusting the bolts P around the slots P, and then setting the holders with reference to the circumferential gradations R at the ends of the drums. It isimportant that the slitting blades should be accurately positioned with respect to the cooperating members U on the lower drum, and to avoid possibility of these parts getting out of alinement they are preferably provided with intermeshing pilot gear segments W. These are secured at the ends of the holders Q, and during the rotation of the drums will engage with each other slightly in advance of the operation of the slitters and remain in engagement until the completion of the slitting and the withdrawal of the blade.

To suit the requirements of the'diiferent sizes of work, exchangeable score bars and slittingblades are rovided, for which suitable selection may he made, and at any time one bar or blade may be replaced with another by merely loosening the set screws Q. Thus, without the necessity of special calculation or high degree of skill on the part of the workmen, the machine may be adapted for any kind of work to be performed.

To avoid the clogging of the machine by the strips of stock trimmed from t-he edges of the blanks, I preferably provide the machine with means into short lengths that they may be more readily disposed of. As shown, 1 is a deflecting finger arranged in the path. of the trimming strip 2 to direct thev latter downward. 3 is a stationary knife adjacent to the path of movement ofthe strip, and 4 is a rotary knife cooperating with the knife3 for cuttlng these strips up to intermittently shear the strip into sections. The rotary knife is driven by any suitable train of mechanism, such as the intermeshing gear wheels 5 and 6.
